Question:
(a) AM radio signals have frequencies between 550 kHz and 1600 kHz and travel with a speed of {eq}\rm 3.0 \times 10^8 \ m/s {/eq}. What are the wavelengths of these signals?
(b) On FM the frequencies range from 88 MHz to 108 MHz and travel at the same speed. What are their wavelengths?
The Speed of Light:
Light is an electromagnetic wave and travels with the speed of {eq}3 \times 10^8 \ m/s{/eq}. The oscillating electric and magnetic fields produce the electromagnetic wave. For an electromagnetic wave, a medium of travel is not necessary, unlike the sound wave. The speed of light is constant. It is proportional to the product of frequency and wavelength.
